how_to Remove an Event Handler

[Z4Zy]

Hello !

when there's an event handler like below,

function vehicleEnter(vehicle,seat)
    if seat == 0 then
        outputChatBox("You have entered a "..getVehicleName(vehicle),source,255,255,0)
	end
end

addEventHandler("onPlayerVehicleEnter",root,vehicleEnter)

we can remove it from one line code like below,

removeEventHandler("onPlayerVehicleEnter",root,vehicleEnter)

So that's all. BUT !,

when there's an event handler like below,

addEventHandler("onPlayerVehicleEnter",root,
function (vehicle,seat)
    if seat == 0 then
        outputChatBox("You have entered a "..getVehicleName(vehicle),source,255,255,0)
    end
end
)

How to remove that event handler ? are there any way ?

You can't remove that. It's an anonymous function, so you don't have the pointer to it (its name). You can't reference anonymous functions, therefore you can't reference it in removeEventHandler.

nope, just separate lines

[IIYAMA]

local handlers = {}
do
 local _addEventHandler = addEventHandler
 function addEventHandler (...)
  local result = _addEventHandler(...)
  if result then
   handlers[#handlers + 1] = {...}
   return result
  end
 end
end

Wrap it.

Just make sure to clean the table once in while.

 

Or get the attached function with this function, if you know the event and the element.

Yet, you can better name your a dogs. If it is called fluffy, then you only have to call 'fluffy, your dinner is ready' and it will surely come back to you.

If you didn't name him, then you have call out like this 'fluffy-dinner is ready'. After that I am not sure how many streetdogs will come back to you. (Not even sure if fluffy would survive that...)
